The invention provides a traffic flow time sequence prediction method and device, a computer system and a computer readable storage medium, and the method comprises the following steps: obtaining a historical traffic flow time sequence in response to a traffic flow prediction instruction; inputting the historical traffic flow time sequence into a classification model to obtain classification labels; obtaining a target prediction model according to the corresponding classification labels; and inputting the historical traffic flow time sequence into the prediction model to obtain a correspondingpredicted traffic flow time sequence. According to the method, firstly, machine learning is carried out on a large number of training time sequences, the mapping relation between statistical characteristics of the training time sequences and the corresponding optimal prediction model is mastered, and a classification model is generated according to the mapping relation and used for outputting theprediction model most matched with the traffic flow time sequence to be detected. Finally, the traffic flow time sequence to be detected is predicted by using the most matched prediction model so asto achieve the purpose of improving the accuracy of the prediction result.
